The structure of the main reducer of different series is different. Its main structure is: driving bevel gear, driven bevel gear, bearing seat, reducer housing assembly and differential assembly. The differential assembly is composed of differential housing assembly, cross shaft, planetary gear , Half shaft gear, planetary gear gasket and half shaft gear gasket. The main reducer is mainly composed of a driving bevel gear and a driven bevel gear. The driving bevel gear is supported on the main reducer housing through two tapered roller bearings and cylindrical roller bearings. The spline part of the front end of the driving bevel gear is equipped with a fork-shaped flange, which is connected with the cross universal joint of the transmission shaft. The driven bevel gear is fixed on the differential housing with bolts, and the differential housing is supported on the final reducer housing through two tapered roller bearings. Two-stage final reducer: In heavy trucks, a two-stage final reducer is often used, as shown in the following figure: The first stage is bevel gear reduction The second stage is ordinary helical gear reduction On a helicopter, the main reducer is an independent part, installed on the upper part of the fuselage? In the reducer cabin, the support is supported on the load-bearing structure of the body. The main reducer is composed of a casing, a reduction gear, a shaft system and a lubrication system. See the outline and partial drawing of the main reducer of a certain helicopter. 1. Carbon wing shaft 2. Rotate the swash plate 3. Installation flange 4. Sun gear 5. Fan assembly 6.

TFT (Thin Film Transistor) is a thin film field effect transistor. The so-called thin film transistor means that each liquid crystal pixel on the Liquid Crystal Display is driven by a thin film transistor integrated behind it. This can Display Screen information at high speed, high brightness, and high contrast. TFT is an active matrix liquid crystal display.
The TFT-LCD liquid crystal display is a thin film transistor type liquid crystal display, also known as "true color" (TFT). TFT liquid crystal has a semiconductor switch for each pixel, and each pixel can be directly controlled by dot pulses, so each node is relatively independent and can be continuously controlled, which not only improves the response speed of the display, but also can be accurately controlled Display color gradation, so the color of TFT liquid crystal is more real.
In the fierce competition among many flat panel displays, why TFT-LCD can stand out and become the next-generation mainstream display is by no means accidental, it is the inevitable development of human technology and thinking mode. The liquid crystal has avoided the difficult light-emitting problem successively, and the light-emitting display device is decomposed into two parts by using the excellent characteristics of the liquid crystal as a light valve, namely the light source and the control of the light source. As a light source, brilliant results have been achieved in terms of luminous efficiency, full color, and life, and they are still being deepened. Since the invention of LCD, the backlight has been continuously improved, from monochrome to color, from thick to thin, from side fluorescent lamp type to flat fluorescent lamp type. The latest achievements in luminous light sources will provide new backlight sources for LCDs. With the advancement of light source technology, newer and better light sources will appear and be applied to LCDs. The rest is the control of the light source, the technology and process of the semiconductor large-scale integrated circuit are transplanted, the thin film transistor (TFT) production process has been successfully developed, the matrix addressing control of the liquid crystal light valve is realized, and the light of the liquid crystal display is solved. The cooperation of the valve and the controller enables the advantages of the liquid crystal display to be realized.
